Photos: Fernando Alonso wins controversial German GP

Fernando Alonso led from pole position to chequered flag to win the German Grand Prix for Ferrari on Sunday while Germany's World champion Sebastian Vettel was stripped of second place for an overtaking infringement.

The Spaniard's third win of the season stretched his championship lead to 34 points and ensured he will stay on top through the European summer break which starts after next weekend's race in Hungary.

Race officials said that Vettel left the track as he passed McLaren's Jenson Button on the penultimate lap in a controversial move.

Vettel handed a 20 second penalty that demoted him to fifth

Vettel, who has yet to win his home Grand Prix and indeed any race in July, went wide as he and the Briton went through a corner side by side. He was handed a 20 second penalty that demoted him to fifth.

Button moved up to second place, ending a run of disappointing performances, and Finland's 2007 Kimi Raikkonen took third for Lotus.

Alonso's win was Ferrari's 219th, the 30th of the Spaniard's career and third of the season.

"That was fantastic again, pole position...victory." he told his team after taking the chequered flag. "Tonight we have some parties at least."

The Ferrari driver now has 154 points to 120 for Red Bull's Australian Mark Webber, who finished eighth. Vettel has 110 after 10 of the season's 20 races.

Button's podium finish a boost for him

Button's podium finish was a boost for McLaren, who moved ahead of Lotus into third place in the constructors' standings, but it was soured for the team by Lewis Hamilton suffering a puncture early in his 100th race and having to retire.

Alonso started on pole and held off challenges from Vettel and then Button as he stormed to victory in warm, sunny conditions, a stark contrast from the heavy rain which fell during practice and qualifying.

Alonso, who won on the last occasion a Grand Prix was staged at Hockenheim two years ago, briefly surrendered his lead after the first of his two pit stops but the double champion otherwise dominated the race despite being under intense pressure throughout.
